1 Introduction to TransportationSystems


3 Chapter 29: Intercity Traveler Transportation: Air

4 Air Traveler Transportation Costs/Financial Situation Air Traveler Transportation and the 30 Key Points -- Stochasticity -- Peaking -- Selecting Capacity -- Network Behavior Land-side Issues -- Airport Access -- Airport Terminal Design Important Issues -- Airport Capacity -- Hub-and-Spoke Operation -- Safety -- Aircraft Technology -- Yield Management -- Understanding the Air Traveler Market Subsidies --Air as an example

5 Airline Costs and Financial Situation Labor Costs Fuel Costs Equipment Costs

6 Reasons for Air IndustryFinancial Problems Competition is the critical element. There are those that would argue that the industry has more capacity than it needs for the demands it serves. Earnings in the airline industry are very sensitive tothe ratio of filled seats to total seats. Once a seat flies empty, the revenue from that seat is goneforever. And airlines, recognizing that fact, havegone through some destructive pricing battles. The airline industry finds it difficult to quickly adjustits fleet size and hence its capacity. The time between ordering new aircraft from themanufacturer and delivery to the airline can be several years. A Trend: Strategic Alliances

7 Air Traveler Transportation and the 30 Key Points Stochasticity Peaking in Demand Selecting Capacity Network Behavior Other Key Points? CLASS DISCUSSION

8 Land-Side Issues Airport Access Airport Location It is door-to-door travel time that matters. Airport Center City

9 Other Points Proximity of Airport to Center City Rail Access to Airports Airport Terminal Design Airports as Commercial Carriers

10 Important Air Issues Airport Capacity Congestion Pricing at Airports Review the concept of congestion pricing and then CLASS DISCUSSION

11 Hub-and-Spoke Airline Operations Seattle San Francisco Los Angeles Washington D.C. New York Boston Hub-and-Spoke as a Cost/LOS Trade-Off Hub-and-Spoke Operations and System Stability

12 Safety Safety is a key level-of-service variable in the airline industry. Although substantially safer than automobile transportation, the fact that the accidents that do occur are big and eye-catching makestravelers very sensitive to safety concerns. The Federal Aeronautics Administration (FAA) in the U.S. has responsibility for regulating airline safety; they also have a charter to promote the airline industry. Some feel there is an inherent conflict in these two roles. CLASS DISCUSSION

13 Aircraft Technology Aircraft Size Short Take-Off and Landing Aircraft Hypersonic Flight The Space Plane Engine and Materials Technology

14 Yield Management in Air Transportation COSTS Total Costs Operating Costs Spill Costs AIRPLANE C APACITY

15 Air Transportation as an Example of Subsidies Subsidies Between long-distance and short-distance passengers. Cost functions look different for long-distance and short- distance passengers, so there may be cross-subsidies. Between business and non-business travelers. Business travelers require flexibility to make plans on very short notice andchange their plans very quickly. The airline industry charges them a premium for thisservice. Among various origin-destination pairs.Customers on the non-competitive routes subsidize those on competitive routes.

16 Flows of Funds in Air Transportation Passengers Airlines Airports Air Traffic Control

17 Subsidies in Air Transportation Passengers Airlines Airports Air Traffic Control Society-at-Large

18 Does Society-at-Large Benefit Enough to Warrant the Subsidy to Air Transportation? CLASS DISCUSSION
